[Freegis-list] Structured Geografic Language for GIS

[Felipe G. Nievinski]

Sorry for the off-topic, just to explain it a little more: LEGAL (which means, in a free translation, "Spatial Language for Algebraic Geoprocessing") is a language, not a piece of software. It is partially implemented in SPRING GIS, and is based on an map algebra for geographic fields proposed by Câmara (1995).

cheers.
Felipe.
